CORE FOR ROLLS.

Specification of Letters Patent.

Patented Nov. 28, 1905.

To all whmn it may concern.-

Be it known that I, CHESTER W. LYMAN, a citizen of the United States, residing at New York, county of New York, and State of New York, have invented certain new and useful Improvements in Cores for Rolls, fully described and represented in the following specification and the accompanyingdrawings,forming a part of the same.

This invention relates to certain improvements in cores for use with web material such, for instance, as paper, cloth, &c.

It is customary in mills to wind web material on tubular cores, the rolls of material being thereafter shipped to the users on the cores, the rolls being mounted by the users on suitable supports, which engage the cores so that the material may be unwound therefrom. Various devices are employed, the purpose of which is to firmly secure the cores to the shafts on which they are mounted to Wind the web material on and unwind it from the cores.

This invention has for its object to produce an improved device for locking or securing cores of rolls to the supports on which they are mounted either for the purpose of winding material thereon or unwinding it therefrom, which shall be simple, and therefore cheap to construct, and which shall be effective in operation.

With this and other objects not specifically referred to in view the invention consists in certain constructions and in certain parts, improvements, and combinations, such as will be hereinafter fully described and then specifically pointed out.

Referring to the drawings, Figure 1 is a sectional side elevation illustrating one form of the improved locking device in connection with a shaft on which the core or shell is supported. Fig. 2 is a section on the line 2 2 of Fig. 1.

Fig. 3 is a side elevation of one formof one of the locking members employed; and Figs. 4 and 5 are perspective and sectional views, respectively, of one form of coacting locking .member employed.

ing device which may be varied widely in its construction and which may be variously located with respect to the shell. In the particular construction selected to illustrate the invention this locking device embodies a stud having a head 2 and a stem 3, this stem being provided with a recess 4, the purpose of which will be hereinafter explained. hen the looking device consists of a stud, it will be firmly secured to the material of the shell in any suitable manner. In the particular construction shown this is accomplished by passing the stem of the stud through the material of the shell, the outer end of the stud being then clenched, as is clearly shown in Figs. 1 and 2, so that the stud is firmly secured to the shell. When the construction employed embodies the invention in its best form, the locking device will be so secured to the shell that the effective locking part will lie in the interior of the shell, thus avoiding any danger of breaking off the locking device or of tearing it loose from or out of the shell in handling. The locking device will be used in connection with a coacting locking member which may be variously constructed; but this member will be provided with a groove or recess with which the effective locking portion of the device on the shell will engage. A convenient and satisfactory form of locking member is that illustrated in the drawings, which consists of a bushing 6, having a collar 7 thereon, this bushing being designed to be firmly secured to a shaft, as 8, or to any other supporting member by means of a set-screw 9 or in any othersuitable manner. The locking member in its best form may be provided with a plurality of recesses 10, two of said recesses being shown, with either of which the locking member on the shell may engage when the shell is shoved onto its support, according as one or the other of the recesses is in convenient position. The collar 7 forms an abutment against which the ends of the shell may bear.

While the coacting locking member above referred to is shown as a bushing located so as to engage a locking projection located near the end of the core, it may, if desired, as be fore indicated, be otherwise constructed or be located at other points on the shaft or other support.

It will be seen that the construction described forms a very simple and at the same time a very eflective locking device for cores and that it is exceedingly cheap in construction.

While the construction illustrated embodies the invention in its best form, it is to be understood that changes and variations may be made in the construction without departing from the invention.

What is claimed is- 1. In a core for rolls, the combination with a shell, of a locking projection carried by the shell and located wholly within the interior of the shell.

2. In a core for rolls, the combination with a shell, of a stud passed through the material of the shell and firmly secured thereto, the head of the stud forming a locking projection.

3. In a core for rolls, the combination with a shell, of a stud passed through the material of the shell and firmly secured thereto, the

head of the stud lying in the interior of the shell and forming a locking projection.

4. In acore for rolls, the combination with a shell, of a stud passed through the material of the shell and secured thereto by clenching, the head of the stud forming a locking projection.

5. The combination with a shell forming a core for rolls, of a locking member extending into the interior of the shell and permanently secured thereto, a shaft, and a recessed locking member coacting with the locking projection.

6. The combination with a shell forming a core for rolls, of a stud passed through the material of the shell and firmly secured thereto, the head of the stud forming a locking projection, a shaft, and a recessed locking member coacting-with the locking projection.

7. The combination with a shell forming a core for rolls, of a stud passed through the material of the shell and firmly secured thereto, the head of the stud forming a locking projection, a shaft, and a recessed locking member secured to the shaft and coacting with the locking projection.

8. The combination with a shell forming a core for rolls, of a stud passed through the material of the shell and firmly secured thereto, the head of the stud lying Within the shell and forming a locking projection, a shaft, and a recessed locking member secured to the shaft and coacting with the head of the stud.

9. The combination with a shell forming a core for rolls, of a stud passed through the material of the shell and firmly secured thereto by clenching, the head of the stud forming a locking projection, a shaft, and a recessed bushing secured to the shaft and coacting with the stud.

10. The combination with a shell forming a core for rolls, of a stud passed through the material of the shell and firmly secured thereto by clenching, the head of the stud lying within the interior of the shell and forming a locking projection, a shaft, and a recessed bushing secured to the shaft and coacting with the stud.

11. The combination with a shell forminga core for rolls, of a stud passed through the material of the shell and firmly secured thereto by clenching, the head of the stud forming a locking projection, a shaft, and a bushing secured to the shaft and having a plurality of recesses therein, one of said recesses coacting with the head of the stud to hold the shell in place.

12. The combination with a shell forming a core for rolls, of a stud passed through the material of the shell and firmly secured thereto by clenching, the head of the stud lying within the interior of the shell and forming a locking projection, a shaft, and a bushing secured to the shaft and having a plurality of recesses therein, one of said recesses coacting with the head of the stud to hold the shell in place.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
